Replication Data for: Antisemitic Attitudes Across the Ideological Spectrum

Concern about antisemitism in the U.S. has grown following recent rises in deadly assaults, vandalism, and harassment. Public accounts of antisemitism have focused on both the ideological right and left, suggesting a “horseshoe theory” in which the far left and the far right hold a common set of anti-Jewish prejudicial attitudes that dis¬tinguish them from the ideological center. However, there is little quantitative research evaluating left-wing versus right-wing antisemitism. We conduct several experiments on an original survey of 3,500 U.S. adults, including an oversample of young adults. We oversampled young adults because unlike other forms of prejudice that are more common among older people, antisemitism is theorized to be more common among younger people. Contrary to the expectation of horseshoe theory, the data show the epicenter of antisemitic attitudes is young adults on the far right.
